Purpose:

  1. Preliminary look at hi/lo multivariate contrast (cross-validated euclidean) in each task.
  2. Preliminary qualitative comparison of effects of prewhitening and pattern standardization on multivariate contrast.

Notes on analyses:

Target TRs:

Contrasts (cross-validated euclidean):

2 Network-level

Estimates are first averaged across parcels within network per subject. Group-level stats and plots are then displayed at the network-level.

2.1 curves

2.1.1 HiLo contrasts

2.1.2 HiLo contrast t-stats (group)

3 parcel-level

3.1 curves

3.1.1 counts of significant effects per TR

3.1.2 runwise univariate ROIs

3.1.3 largest 20 ROIs

3.2 maps (target TRs)

Unthresholded and thresholded t-statistics. Threshold at fdr-corrected p-value (across all parcels) of 0.05.
